GNS430W通信导航收发机故障分析及排除方法研究

GNS430W Communication&Navigation Transceiver Fault Analysis and Troubleshooting Method Research

文章对GNS430W通信导航接收机的主要故障及排故方法进行了研究,该型设备集通信和导航两大功能于一体,通过对其基本原理和故障统计数据进行分析,将该型机件分模块进行几种典型故障分析,通过故障隔离的方法将维修故障分离到相应模块,再在相应子模块的基础上通过电路原理分析,找出故障电子元器件,为该型机载设备的排故及修理提供便利。

In this paper,the main faults and troubleshooting methods of GNS430W communication and navigation receiver are studied.This type of equipment integrates the two functions of communication and navigation.Based on the analysis of it's basic principles and fault statistical data,analysis several typical fault by divided this type of part into several modules.By using the method of fault isolation,isolate the maintenance faults to the corresponding modules.And then on the basis of the corresponding sub-modules,through the circuit principle analysis,find out the faulted electronic components,and provide convenience for this type of airborne equipment troubleshooting and repair.
